No Drawing.

M invention has reference to a preparatlon, its formula and the process'of makingsame in which the characteristic proper- 'ties of a face powder anda skin bleach are combined so that the skin will retain or acquire a desirable grade of whiteness and the powder will adhere to the skin for the purpose of improving the appearance of the skin and protecting it from the influences of the weather, etc.

To attain temporary improvement of the appearance of the skin it is customaryto apply what is commonly known as face powder. The same adheres to the'skin and affords at the same time a protection against sun and windburn, tanning and freckles. However, this protection is' insufiicient actually: offset these influences.

On the other hand itis customary to apply lotions or greasy creams containing some derivative of lemon or other substance which have the property of bleaching and whitening the skin, if the removal of tan, sun'- or windburn or the bleaching of freckles is .desired. This necessitates an extra applica-' tion of such preparations usually 'at night time when such procedure is rather unwelcome. Furthermore, these products usually leave. a film of grease on the skin which rubs ofi' gradually during the night, soiling bed linen, etc. And finally they involve an additional expense.

In consideration of these above mentioned and many other disadvantages such as the not to everyone leasant odor of lemon; the danger of app ying preparations which oftentimes contain mercurial compounds,

etc., I have produced a preparation which will do away with-all these disadvantages, inasmuch as it combines the distinctive properties .of a face powderwith the properties of a. skin bleach in one.

In preparing the composition I' prefer to use the ingredients named below in about the following proportions, as giving the best results--viz, per cent talcum, 10 per cent precipitated chalk, 10 per cent magnesium carbonate, 5 per cent zinc stearate and 8 per cent zincoxide, combined'with a skin each composed of approximately the following formula-8 per cent zinc perborate,

4 .per cent sodium peroxide and a suflicient quantity oil of lemon.

The reason for following the above formula in preparing theproduct is that tale is this property Application filed August 12, 1922. Serialjlq'o. 581,551.

giving a body to the powder at the same time assuringsoftness of texture and giving a certain degree of fattiness to the powder. The'proportion of course may be varied in accordance with the-qualities of above description desired to predominate in the finished.

product. The chalk is used to aid in "produclng adhesiveness, giving a desired consistency and to allow better the Working of the powder into cake form if so desired.

- stance, orris root and other products will produce similar results and therefore may be.

substituted. Zinc oxide is used on account of its beneficial effect of healing and soothing. nature to the skin; and furthermore,'

on account of its increasing the adhesiveness I of the powder. The quantity required depends upon the extent to which the above qualities. are desired to predominate in the finished product. Of zinc stearate the same is true that was said about the zinc oxide; in addition to which it gives a certain amountof fattiness to the powder. It may be eliminated or reduced in quantity where is desired in a different degree than I consider preferable. In my opinion, the most preferable inredients to form an effective and yet harm'- ess skin bleach which may be combined with a face powder are either zinc rborate or sodium peroxide, or'both. T eir outstandin properties as bleaching chemicals are mildness, and therefore I prefer to use said products in preference overother chemical compounds, which, however, may

be substituted by such other chemicals as have a similar therapeutic action. The addition of lemon oil'is not essential, and

therefore, may be eliminated or substituted. However, I'prefer to-incorporate the same in my product, as it has initself a bleachface powprovide forthe addition of suitable coloring matter to produce such shades as may be-desired.

The process I have found most suitable and therefore which I prefer to use is as follows: The ingredients comprising the face powder are sifted by means of suit able machinery in order to assure the desired fineness and thereafter they are mixed thoroughly in suitable machinery. On the other hand, the zinc perborate is also put through a sifting process in order to assure sufiicient fineness. The same is then rubbed up with lemon oil, while the sodium peroxide is dissolved in water. After this, the mixture of zinc perborate and lemon oil is worked up with the face powder by mix ing, milling or other suitable means of combining, and the sodium peroxide solution is then sprayed into the powder by means of suitable equipment. To assure more thorough mixing, as well as extreme fineness of the powder, I prefer to put the product throu h a blowing or air float process, and thereafter it again is put through a sifting and mixing process 'by means of suitable machinery.

The perfume and color are added to the face powder before the bleach is incorporated.

The final step in the process is to subject the powder to a drying process, and it is then ready for use in loose form. If it is desired to produce what is commonly called a compact or cake, the powder is subjected to a special process to produce such cake.

The compound which I have invented can be conveniently carried about and is available at any moment desired for the purpose of retouching the skin and serves asa protection against-sunburn, wind, tanning and freckles, as it will counteract these influences rather than merely forming a protecting film of powder on the skin. In other words it assures an improvement in the appearance of the skin which is apparent after the removal of the preparation from the skin. It offers a more effective protection than face powder against the influences of the weather, aside from the fact that it counteracts those influences, and it is a compound that may be agreeably applied. Besides which it saves the user the inconvenience and expense of purchasing two distinct products in separate containers for the purposeof obtaining the effects of a skin bleach and a face powder.

What I claim is:

1. A cosmetic compound comprising approximately 85 to 95 per cent of a face powder, and approximately 5 to 15 per cent of a skin bleach, said last named element being composed of zinc perborate and SOdl-r um peroxide in the proportion of 2 to 1 and having a quantity of oil of lemon incorporated therewith.

2. The process of preparing a cosmetic compound, consisting in suitably mingling a face powder containing powdered talc,

precipitated chalk, magnesium carbonate,

zinc stearate and zinc oxide;-a skin bleach containing zinc perborate, sodium peroxide; and oil of lemon, in suitable proportions as described,

3. The composition of matter consisting of a combination of a face powder with a skin bleach, said skin bleach including zinc perborate, sodium peroxide, and oil of lemon, whereby to produce a preparation displaying the property of a face powder'and a skin bleach combined.
